To sum it up, basically the only class you need(ed) a laptop for last year was 1P03.. if you went, LOL. That was a miserable class, lectures sometimes had <10 kids lol.
Anyways, most courses have notes you can print before hand. 1p03 required us to take our own notes.. which was annoying since first term he refused to post up the slides.. 2nd term he kinda did.
I took my laptop to classes like 1E03, 1D03 (physics) and found it beyond useless, since the prof does examples on the board.
Best place for a laptop i found was the 1P03 tutorials that take place 2nd term
--To sum it up, no, a laptop is not required in class
